Should your local community expand efforts to convert organic waste into usable energy?

The American Biogas Council released a comprehensive report identifying 1,213 wastewater facilities that currently utilize anaerobic digestion to process organic waste. These facilities collectively capture approximately 100.8 billion cubic feet of biogas annually.

Why it matters

The findings underscore the role of wastewater infrastructure in renewable energy production, highlighting a significant opportunity to scale biogas capture for heat, electricity, or renewable natural gas. Expanding these systems could nearly double the current energy output from these sites.

Current operations capture 100.8 billion cubic feet of biogas, providing enough energy to power 1.1 million homes. The report suggests total capture potential could reach 172 billion cubic feet, enough to supply 1.9 million homes.

American Biogas Council

This trade association represents the biogas industry in the United States and advocates for policies that promote renewable energy production.

The details

Anaerobic digestion involves breaking down organic materials within wastewater to generate energy, a process practiced at sites ranging from modern plants back to the earliest identified facility in 1914. While 139 facilities currently co-digest external organic waste, more than 75% of large plants processing over 30 million gallons per day utilize this technology.

The earliest identified facility with an anaerobic digester began operating in 1914.
The American Biogas Council conducted its research over an 18-month period from 2024 to 2026.
The comprehensive assessment was published on October 5, 2026.

Market Landscape

This study updates national renewable energy data by establishing the American Biogas Council's 2026 anaerobic digestion survey as the primary benchmark for wastewater energy potential. It highlights a clear path for utility operators to increase market share by expanding co-digestion capabilities.

Greater adoption of anaerobic digestion at local wastewater plants could lead to increased production of renewable natural gas and electricity for the public grid. Residents may see long-term benefits in energy sustainability as more facilities integrate organic waste processing into their operations.

The takeaway

Wastewater facilities are evolving from simple waste treatment sites into significant contributors to the national renewable energy supply. Operators can look toward co-digestion of organic waste as a proven method to boost energy output and operational efficiency.
